Scope

Scope: This standard applies to the exhaust gas generated during the chlorination (nitrochlorination reaction) process. The nitrogen oxides (NO, NO2) in the exhaust gas are absorbed by sulfuric acid to obtain co-produced nitrosyl sulfuric acid, which is mainly used as an industrial raw material for diazotization reactions. Main technical content: This standard specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, storage, and safety of co-produced nitrosyl sulfuric acid from chlorination.
